Among the better ways of guessing your chances is to compare yourself to the students they did accept. Here's how the middle half of their most recent Freshman class did:

SAT – Critical Reading Middle 50%:670-750
SAT – Math Middle 50%:670-740
TPR Projected Range SAT Writing:690-750
Students in top 10% of HS class:80%
Total applicants who are accepted:27%

Your extracurricular activities look good, but your test score really does need to come up to the level you intend to aim for, if not higher. That middle half's scores ranged from 2030 all the way up to 2240, so your projected 2100 is at the lower part of the range.
